At a parameter such as ISO, everyone at least once "ran into" the menu of his camera. However, not everyone knows about it. Let's see what is ISO in the camera.
This parameter hides the photosensitivity of the camera. The sensitivity is higher, the higher the value of the specified parameter, and from the high value in the picture there is a lot of noise. That's why experts recommend using a low ISO value to get quality photos without noise. When shooting in low light without a tripod, increase the value of this parameter. If the aperture is also fully open, you can increase the shutter speed so that the photo does not get blurred. If we talk about what ISO is in the camera, it should be noted that when shooting at night, it is still necessary to use a tripod, and also set the value of this parameter below. When using a flash in its high value, there will be no need.
It is worth noting that the amount of noise on a photograph at a high ISO value depends directly on the size of the matrix used in the camera. If these are compact cameras, then with ISO 800 it is not necessary to expect a good result. Poor lighting will cause the photo to be completely smeared. In this case, the camera should be held on a tripod using a low parameter value. When working with professional or semi-professional technology, you can set its value four times higher, while the quality of the pictures will be simply stunning.
Speaking of what ISO in a camera is, it's worth remembering such an option as Auto ISO. It can be noted that this function is quite capricious. If you use a soap box, you should set ISO 100 and not bother. When using a SLR camera, you can limit Auto ISO to certain limits. For example, you put the highest value at 800, then the camera will not be able to raise it higher, even if it is appropriate.
If we talk about what ISO is, we should also note that the values of this parameter can be quite diverse. In modern cameras there are a number of values within the range of 50-204800. Amateur band usually ends at around 1600, and for more advanced cameras it reaches 3200. At higher values, there is no sense in ordinary life, they can come in handy for shooting shooting done on professional cameras.
If you use digital cameras, then there are certain places where high ISO values can come in handy. First of all it should be said about activities with active actions, premises where flash can not be used for one reason or another, but at the same time lighting in them is not of high quality. When shooting a night city, it is better to use a tripod, while setting a high value of photosensitivity, but not using a flash.
Now you know what ISO is in the camera.
